believe me if you begin to play other campaines you learn to read the textes and use f4 if the text disappear to fast, in the missions
and if you use the english stu_fs2.vp, you got the german text and the english voices, its the best compromise, in my opinion.
to the voices: the german version of petrach sound imho better as the english one, in german he sound older and more powerfull as in english.
the communication officer or co of the colossus sound imho really identical to the english orginal speaker, bored and frustrated
spikes sound cool in german, too
but the rest of the voices i prefer the english ones.
and yes its sucks that in german the briefings and the debriefings doesnt have voice
